检查服务器实现的vllm/entrypoints/api_server.py。服务器使用AsyncLLMEngine类来支持异步处理传入请求。 启动 服务 默认情况下,此命令在启动服务器http://localhost:8000OPT-125M型号。 调用服务 curl http://localhost:8000/generate \ -d '{ "prompt": "San Francisco is a", "use_beam_search": true, "...
针对你遇到的vllm.engine.async_llm_engine.AsyncEngineDeadError: Background loop has errored already错误,以下是对该问题的详细分析和解决方案: 1. 错误信息含义 AsyncEngineDeadError是vllm引擎中的一个错误,表示异步引擎的后台循环已经出错。这通常意味着在后台处理请求的过程中发生了某些异常,导致引擎无法继续正常...

* fix: use vllm AsyncLLMEngine to bring true stream Current vLLM implementation uses the LLMEngine, which was designed for offline batch inference, which results in the streaming mode outputing all blobs at once at the end of the inference. This PR reworks the gRPC server to use asyncio ...

量化流程梳理如下：1. 获取参数：创建LLM或AsyncLLMEngine类，配置包括设备、模型、缓存等参数。选择分布式框架Ray根据是否多卡。2. 创建Engine：初始化GPUExecutor，该类管理GPU任务和cache处理。创建LLMEngine，构建组件如TokenizerGroup、Detokenizer和GPUExecutor。3. 初始化环境与加载模型：统计内存，加载模型...
